Anodyne In The Afterlife

The heavens and hell have united and every soul goes to the layer of Limbo, Which is divided into 14 cities, 7 of sins and 7 of virtue, Every soul goes to one of them, But one day a man named Zen comes, he didn't fit anywhere, afterall he was a neutral anomaly, one day he finds a job as Envoy, And now he goes around the cities to complete missions.
